Several major companies are secretly recording your every move on their iPhone apps without your permission or even your knowledge, a new investigation has found.

According to the TechCrunch report, several popular iPhone apps, including hotels and travel sites and retailers, not only know what you're doing with their apps but they could even expose sensitive data.

The technology news site discovered that apps including Hotels.com, Air Canada and Abercrombie & Fitch use Glassbox, a customer experience analytics firm that allows developers to embed so-called "session replay" technology into their apps. Developers can then record users' screens and play them back to see how people used the app.

"Every tap, button push and keyboard entry is recorded—effectively screenshotted—and sent back to the app developers," TechCrunch reports.
